Zusammenfassung: | PURPOSE:To uniformize the chemical composition of the adding metal in a welding metal and to improve the joint performance of a weld zone by executing a metal adding electron beam welding, projecting the electron beam in plural times on the weld zone as well and remelting the molten metal. CONSTITUTION:The body 1 to be welded is welded by projecting an electron beam 2 by using a filler wire, etc., to form the electron beam welding metal 6 to which a metal is added. The electron beam 2 is then projected in plural times on the same line or at its vicinity. Said welding metal 6 solidified by this projection is remelted to promote an agitation and the uniformity of an additive is advanced by increasing the number of remelting times. The uniformization of the adding metal chemical composition in said welding metal 6 is thus achieved and the joint performance of the weld zone can be improved. |
